Title: Liquid crystal display device
Inventor: HAMAYA TOSHIJI
IPC: G06F1/16
Filed: 1988-07-19
Abstract: PURPOSE:To restrain an increase in power consumption without affecting the advantage of a thin liquid crystal display by mounting a solar battery on the rear surface of a liquid crystal display substrate. CONSTITUTION:The solar battery 11 of size equal to or larger than a substrate 9 is mounted on the rear surface of the liquid crystal display substrate 9. The battery 11 is used for directly driving the device or charging it. To take in light from both sides of the substrate 9, the solar battery 11 composed of amorphous semiconductor layer 13 is employed. A transmission type display has a light source therein, and lights emitted therefrom include light contributing to liquid crystal display by characters and figures, and light irradiating a decorative sheet, etc., on the rear surface of the display device. These lights turn into heat in these parts and are not used effectively. However, by imparting transmissivity to the electrodes 19 and 21 of the solar battery 11, these useless lights can be recovered, and the recovered power can be used for liquid crystal display, whereby the total power consumption can be minimized.

Title: Steering controller for self-traveling work vehicle
Inventor: NAKAZAWA MASAAKI
IPC: G05D1/02
Filed: 1989-07-12
Abstract: PURPOSE:To keep a self-traveling state of a self-traveling work vehicle whithout causing a big error of the traveling direction of the vehicle even if the detection of the position of the vehicle attained by a self-position sensor is temporarily disabled by using a self-position arithmetic means. CONSTITUTION:A self-position arithmetic means is set into a control unit 8. If the self-position detecting operation of a photoelectric sensor 5 is temporarily disabled by the disturbance, the average azimuth is operated based on the azimuth detecting information detected by an azimuth sensor 6 right before the self-position detection is disabled and the azimuth detecting information detected at present by the sensor 6. Then a self-position arithmetic means operates the self-position of a vehicle based on the latest self-position detecting information detected right before the detection unable state, the average azimuth information, and the vehicle traveling speed information detected at present by a vehicle traveling speed sensor. Thus it is possible to keep the self-traveling state of the vehicle with no big error caused in the traveling direction even if a self- position detecting operation attained by the sensor 5 is temporarily disabled.

Title: Semiconductor package
Inventor: NAKAGAWA SHOICHI
IPC: H01L23/50
Filed: 1987-07-18
Abstract: PURPOSE:To relieve an effect of molding stress at the time of a bending operation so as to upgrade reliability and to stabilize quality, by projecting an outer lead from a main body of a semiconductor package and bending/molding the lead in the vicinity of a side end of the main body and on a position of a groove formed on a surface in the bending direction. CONSTITUTION:A groove 5 is formed beforehand on a bending position 4 and on a surface in the bending direction of an outer lead 3. Since the groove 5 exists in this way upon the bending/molding of the outer lead 3, bending stress becomes small and so a bending operation is facilitated. Accordingly the bending stress has no effect on the inner lead. Hence the bending formation of the outer lead is facilitated, and the effect of the bending stress on the inner lead is much relaxed, so that mold resin is prevented from cracking and damp-proof performance is prevented from being lowered due to deterioration in adhesiveness between the mold resin and the inner lead.

Title: Foreign object removing device for inside of water flow pipe
Inventor: HASHIMOTO TAKAO
IPC: F16L55/24
Filed: 1993-06-25
Abstract: PURPOSE:To guarantee the water quality by means of removing foreign matters included in a water flow pipe and simplify ultimately the maintenance works of a foreign matter capturing means. CONSTITUTION:Foreign matters are captured by a filter 4 and accumulated there. Any arbitrary inside surface (a) of this filter 4 surrounded by a low pressure backwash chamber 6 connected with the outside receives a backwash action based upon the static pressure of the streaming water. The foreign matters are removed from the inside surface (a) of the filter member and move into the backwash chamber 6. The matters in the chamber 6 are exhausted to outside of the water flow pipe 1 by the opening/closing operations. With the movement, the backwash chamber 6 can cover the inside surface of the filter member 4, so that the foreign matters accumulated on the filter 4 are removed completely.

Title: Elliptical rotary compressor
Inventor: FUNAKOSHI TOYOMATSU
IPC: F04C18/46
Filed: 1987-07-17
Abstract: PURPOSE:To improve efficiency as well as to lessen costly procedures by providing both a rotor rotating toward the tip end by way of the sliding surface of a vane shaft direction so as to perform suction and compression and a channel between the vane and a casing. CONSTITUTION:An elliptical rotor 2 is rotated about a driving shaft 16 within a cylindrical casing 1 so as to perform suction and compression. When the rotor 2 is rotated, C chamber is under compression allowing a leaf spring 7 to be opened upon an increase in pressure higher than E chamber for letting air flow into E chamber through a gap between a vane shaft 5 and the casing 1. When the pressure in E chamber is increased, the compression work for C chamber is completed. Compression is performed two times for every one revolution of a rotor 5 as if two cylinders were operated because two vanes 5 are mounted at the symmetrical right and left sides. This constitution enables compression efficiency to be improved, thereby enabling costly procedures to be lessened.

Filed: 1980-12-19
Abstract: PURPOSE:To inspect circuit elements such as diodes and the like without cutting off a circuit, by inspecting a circuit in parallel connection of inductance elements and diodes via an operational amplifier and maximum and minimum value detecting circuit. CONSTITUTION:A circuit to be inspected in parallel connection with an inductance element of an inductance L and a diode 5 is connected with an output of an operational amplifier 3 and an its inverting input terminal, and a trapezoidal pulse from a pulse generating circuit 1 via a resistor R1 is applied to the inverting input terminal. Thus, as a current (i) flowing to the resistor R1 is increased/ decreased with time, a voltage V2 based on EquationIis outputted from the amplifier 3 (in Equation, VF is a forward voltage of the diode 5). When the output voltage is detected at a positive/negative peak voltage detection circuits 8, 9 which are controlled switchingly, a specified detected output is produced from a voltage measuring device 11 only at normal state, allowing to inspect circuit elements such as diodes without cutting off the circuit.

Title: Scroll device with pressure regulator
Inventor: DERUMAA AARU RIFUI
IPC: F04C18/02
Filed: 1989-07-14
Abstract: PURPOSE: To apply regulated pressure by constituting a pressure regulation device with a piston inserted in a hole to vary the size of a discharge aperture from a discharge pressure chamber in response to a first inner end plate exposed to discharge pressure and a second outer end plate exposed to suction pressure. CONSTITUTION: A piston 180 is moved inwardly and outwardly in a regulation passage hole 106 to increase or decrease the usable flow area in response to the pressure differential between the suction pressure and discharge pressure. In this case, the increase in discharge pressure agitates the piston 180 to increase the useable flow area. The relative decrease in discharge pressure agitates the piston to decrease the useable flow area. Thus, as a result of the agitation of the piston, the piston acts to increase the discharge pressure fluid held in the chamber when discharge pressure is decreased, and on the contrary, when discharge pressure is decreased in the chamber, the piston acts to decrease the discharge pressure to allow a great amount of flow.
